Declines in skeletal muscle quality vs. size following two weeks of knee joint immobilization [PDF]

open access: yesPeerJ, 2020
Background Disuse of a muscle group, which occurs during bedrest, spaceflight, and limb immobilization, results in atrophy. It is unclear, however, if the magnitude of decline in skeletal muscle quality is similar to that for muscle size.

The contribution of the tendon electrode to M‐wave characteristics in the biceps brachii, vastus lateralis and tibialis anterior

open access: yesExperimental Physiology, 2023
In some compound muscle action potentials (M waves) recorded using the belly–tendon configuration, the tendon electrode makes a noticeable contribution to the M wave. However, this finding has only been demonstrated in some hand and foot muscles.

Neuromechanical Properties of the Vastus Medialis and Vastus Lateralis in Adolescents With Patellofemoral Pain

open access: yesOrthopaedic Journal of Sports Medicine, 2023
Background: An alteration in the force distribution among quadriceps heads is one possible underlying mechanism of patellofemoral pain. However, this hypothesis cannot be directly tested as there are currently no noninvasive experimental techniques to measure individual muscle force or torque in vivo in humans ...
